A new report says Healthcare.gov remains vulnerable to hackers.

FOX's Rachel Sutherland reports from Washington:

The Government Accountability Office says the Obamacare website has logged more than 300 security incidents over the past 18 months.

Most of them involved electronic probing by hackers, but none of the incidents appears to have led to the release of sensitive information like names, birth dates or social security numbers.

Although GAO said the Obama administration is making progress, its report concluded that security flaws "will likely continue to jeopardize the confidentiality, integrity and availability of HealthCare.gov."
